In the present study, an attempt has been made to analyze the temperature and rainfall extremes observed in Gujarat during the recent past. Observed daily data of maximum and minimum temperature and rainfall for 32 geographically well distributed locations in Gujarat for the available time series during year 1958 to 2011 has been used to calculate various extreme climate indices and their trends. Results revealed signature of warming in Gujarat as indicated by statewide uniform increase in numbers of warm nights (TR25), decrease in cold days (FD10), decrease in frequency cool nights (TN10p), increase in minimum of minimum temperature (TNn) and increase in frequency of warm nights (TN90p). The results also indicated an increase in total amount of precipitation (PRCPTOT) and extremely wet days (R99p) over more numbers of stations of the state. However, most temperature and rainfall extremes showed mixed over the state.
